Report: Adelson's new donation to Newt super PAC arrives

Casino mogul and major Republican donor Sheldon Adelson made an expected new contribution this week to the super PAC supporting Newt Gingrich, Winning Our Future, CNN has learned. One source familiar with Adelson's donation described it as "sizeable." Two sources said the Nevada businessman made the contribution recently.

The sources would not speak on the record because Adelson wanted his contribution to be private.

CNN reported last week Adelson was expected to contribute as much as an additional $10 million to the super PAC. A great majority of the funding for Winning Our Future has come from Adelson and his extended family. Adelson, his wife and their extended family have donated $11 million to the organization.

The sources would not specify the exact amount of the donation.

It would not be a surprise if Adelson continued to help out his friend Gingrich, who, by all accounts, he feels great affection for, despite his lack of a clear path forward in the 2012 race right now. But the fact that Adelson, who has publicized has past WOF donations, does not have anyone close to him announcing it indicates that any new money is being done in a quiet way so as not to embarrass or wound Mitt Romney.
